On the last day of 2010, it’s time for us to reflect on the past year of Google blogging. This year, we published 454 posts (including this one) on the Official Google Blog—7 percent more than 2009. Those posts had an astonishing number of readers: 24,768,052 unique visitors stopped by this year, more than 70 percent more than last year. (The huge increase is mostly due to this year’s April Fools' post, which benefited from a link in a prominent location; more on that below.) People come to the blog from all around the world; the top countries sending visitors in 2010 were the U.S., U.K., Canada, India and Germany, but readers came from dozens of other places as well.

The top posts this year run the gamut from policy changes to product arrivals:

A different kind of company name - 10,604,183 unique pageviews, more than 30 percent of the year’s total. Our April Fools' Day post about changing our company name to “Topeka” had a crazy-high number of pageviews, in large part because there was a link to our humble blog on Google’s homepage that day. That’s a lot of eyes!

A new approach to China - 924,335. We post about our new approach to business in China; we will no longer censor search results on Google.cn.

Introducing Google Chrome OS - 653,803. This post introducing our open source operating system was published in July 2009 (and was the top post of 2009), but continued to draw readers this year. (This month, we launched a pilot program for Chrome OS notebooks.)

Speaking of Twitter, this was our second year of tweeting officially on @google. We crossed the 2,000-tweet mark earlier this month and now have more than 2.6 million followers. Our Twitter family grew by leaps and bounds as well—you can now follow Google on more than 100 Twitter accounts posting news of all kinds, from API updates for developers to product news in countries around the world. Twitter was also our biggest referrer to this blog in 2010 (excluding Google search, Google properties such as google.com/places and Feedburner)—followed closely by Facebook.

As always, we’re grateful to all of our readers for keeping up with us over the year, and we’re looking forward to bringing you more news in 2011!
